IMPROVEM ENT IN COOKING-SITOVES.

Specification forming part of Letters Patent N0. 140,044, dated J une17, 1873; application filed April 3, 1873.

To all whom it may concern:

Be it known that I, JAMES R. HYDE, of Troy, in the county of Rensselaerand in the State of New York, have invented certain new and usefulImprovements in Stove; and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings and to the letters of reference marked thereonmaking a part of this specification.

The nature of invention relates to an improvement on Letters Patentgranted to me for an improvement in stoves, dated March 11, 1873; and itconsists, first, in providing the fire-box with an air-chamber aroundall of its sides, said chamber communicating with a cold-air ductextending through the bottom plate of the stove, and with a flue at itsrear which leads into a flue in the bottom plate of the stove forsupplyin g heated air to a reservoir in the rear of the stove, and atthe same time giving additional heat to the oven; second, in theconstruction of the flue in the bottom plate of the stove; third, in theconstruction of the flue in the back end of the stove.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe it-sconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a longitudinal vertical section of my stove. Fig. 2 is aplan view of the same with the top plate and fire-box removed. Fig. 3 isan inverted View of the perforated rim above the fire-box. Fig. 4 is aview of the stove-back and Fig. 5 represents the device for attachingthe reservoir to the stove.

In the accompanying drawing, A represents the top plate of a cook-stove,made in any of the known Ways. B represents the oven-top; C, thelire-box; D, the ash-pit; E, the oven; F, the common two or three flueunder said oven; P, the common back flue; I, the reservoir attached tothe rear of the stove; I', the warming-chamber, placed under saidreservoir; and M, the stovepipe. Around the fire-box C is formed anair-chamber, a, extending entirely around the same, and provided with avertical partition, b, as shown in Fig. 2. Cold air is admitted intothis chamber through a duct or flue, d, on one side of the partition b,said duct extending down through the bottom plate G of the stove andtaking in cold air at the bottom. The cold air, passing entirely aroundthe fire-box, becomes thoroughly heated and passes down through a flue,e, on the other side of the partition b. This flue e leads into a ue, f,formed in the bottom plate G of the stove. The liuc f, at its front end,or where it communicates with the vertical flue e, is extended to, ornearly to, the entire width of the bottom plate, and then contractstoward the rear, as shown by the dotted lines in Fig. 2. By thisconstruction of the tlue f, as well as of the flue h, hereinafterdescribed, additional heat is given to the oven. The rear end of theflue f communicates with a vertical'iiue, h, in the back plate H of thestove, to supply heated air to the reservoir in the same manner asdescribed in my former patent above referred to 5 but in this ease thelue h is extended in width in elliptical-shaped form, as shown in Fig.4, and then contracted toward its upper end, whereby the back of theoven obtains additional heat, the bottom of the oven being givenadditional heat by the construction of the ue f. On the top edges of thefire-box C is placed a perforated rim, J, forming an air-chamber, t',between it and the stove-body, into which chamber air is admittedthrough a flue or pipe, m, extending through the bottom of the stove. Apartition, n, is made in the chamberi near the entrance of the pipe ordue m, to cause the air to pass entirely around, and then through theperforations, thereby supplying cold air to the lire for consuming thegases arising from the combustion of the material in the re-box. Theside edges of the top plate A are extended toward the rear beyond theback plate H of the stove, forming ears p, each of which has a notch orrecess cut in its inner side, as shown in Fig. 5. On each end of thereservoir I, Vat the upper front corner, is cast a lug or projection, s,and along the entire front side of the reservoir a suitable distancefrom the top edge, is formed a shoulder or offset, a'. The reservoir Iisattached to the back of the stove by the lugs or pro iectons a c ttingin the notched or recessed ears p p, and the shoulder :c resting on therear edge of the top plate A.

By this means the reservoir can easily be attached and detached, whendesired. W hen the reservoir is not in use, and detached, a bar,properly shaped, may be used to llll out tbe space between the two earsp p.

llvin thus fully described my invention, what I c aim as new, und desireto secure by Letters Patent, is4

l. The combination, in a reservoir cookingstove, of an arehambersurrounding the drebox, s cold-nir duct lending into the mme, and u dueor tine leading from the chamber nud conveying hentai nir directly underthe reservoir.

2. The ue f, in the bottom plate G, extended in width at the front end,and contracted toward the rear, as and for the purposes specified.

3. The flue h, in the back plate Il, made in ellgtical shape, ns and forthe purposes speci In testimony that I claim the foregoing l havehereunto set my hand this 2d dny ol` April, 1873.
